Definitions
- the present invention relates to the use of thiamphemcol and de ⁇ vatives thereof for the preparation of pharmaceutical compositions useful in the treatment of Chlamydia pneumomae infections
- Chlamydia pneumomae is an intracellular bacte ⁇ um recently considered responsible of respiratory infections both of the upper tract and the lower tract This bacte ⁇ um is one of the most widespread human pathogens and p ⁇ mary infections in children from 5 to 14 years have been supported by documentary evidence In children the infection is generally mild and asymptomatic, but can be more se ⁇ ous in adult and elderly Chlamydia pneumomae is responsible for about 10% of cases of atypical pneumonia and of 5% of cases of bronchitis It has also been associated with respiratory airways diseases and with new onset asthma and asthmatic bronchitis in the adults Sinusitis caused by Chlamydia pneumomae also associated with infections of the lower respiratory tract has been descnbed and, moreover, Chlamydia pneumomae has been isolated from middle ear fluids of patients with otitis media For a survey of the pathologies associated to Chlamydia pneumomae infections see F
- azithromycm and, in particular, cla ⁇ thromycin resulted active in vitro against Chlamydia pneumomae and others agents involved in these infections and therefore they are potential therapeutical agents in the treatment of Chlamydia pneumomae infections
- compositions useful in the present invention are compositions for enteral or parenteral use containing thiamphe col or de ⁇ vatives thereof such as, for example, thi- amphenicol glycinate and salts thereof
- thiamphemcol glycinate acetylcysteinate is particularly preferred.
- the amount of active ingredient, expressed as thiamphenicol, contained in the pharmaceutical composition may change depending on the administration way and on the senousness of the infection but is generally comprised between 250 mg and 5000 mg per dose, more preferably between 500 mg and 2000 mg
- the pharmaceutical compositions can be in a solid or liquid form, suitable for administenng by lnjectable, oral or aerosol route
- Preferred are the pharmaceutical compositions suitable for administenng by aerosol or m- jectable route
- More preferred are the pharmaceutical compositions suitable for administenng by aerosol or m j ectable route containing thiamphemcol glycinate hydrochlonde or acetylcysteinate
- Particularly suitable are the pharmaceutical compositions already on the market with the trademark FLUIMUCIL ANTIBIOTICO ® and GLITISOL ®
- thiamphemcol efficacy against strams of Chlamydia pneumomae of recent clinical isolation has been demonstrated in vitro by calculating the MIC (Minimum Inhibitory Concentration) in compa ⁇ son with other antibiotics It is important to underline as thiamphemcol showed a MIC completely comparable, or better, with respect to that of reference antibiotics already used in therapy for the treatment of Chlamydia pneumomae infections
- Chlamydia pneumomae strams Chlamydia pneumomae TW183 and Chlamydia pneumomae 2023 were obtained from American Type Culture Collection The other strains (No 9 isolated) were clinically isolated ln the penod 1997-1999 Antibiotics
- Monolayers of Hep-2 cells were prepared by seeding 2 x 10 5 cell/ml in EMEM with 10% fetal calf serum supplemented with L-glutammine, on 12 mm cover slips and left at 35°C, 5% C0 2 for 24 to 48 hours for confluent growth The growth medium was removed and Hep-2 monolayers were inoculated with the different strains at predeterminated concentration calculated to give 3-5 x 10 2 inclusions for well
- the monolayers, moculated with Chlamydia pneumomae were centnfuged at 1700 g for 60 minutes at 30°C Supernatant was removed and was replaced with 2 0 ml of EMEM containing 2% fetal calf serum, L-glutammine, cycloheximide 1 ⁇ g/ml and different dilutions of the tested antibiot- ICS
- Clanthromycin and thiamphemcol glycinate acetylcysteinate are the most active anti- biotics (MIC range 0 03 and 0 25 ⁇ g/ml for both)
